Abstract
Light-matter interactions between the metallic and dielectric layers along with the controlling of electromagnetic waves can create a way to develop micro-devices and moderate the functionalities for advanced applications. This study describes a new controlling technique of the plasmatic electron packet based on an electric split-ring resonator (eSRR). All numerical experiments were performed using an advanced CST electromagnetic package. The proposed metamaterial tunneled structure in this study operates using terahertz (THz) frequency spectrum as an efficient digital processing filter. The array combination of the tunneled structure consisted of three individual unit cells. Moreover, the two engineered metallic arms added to the tunneled structure exhibited two peak resonances and one passband frequency region. A large evanescent field was produced to enhance the wave-metal interactions with the presence of a metal-dielectric micro-tunnel. The intensity of the electromagnetic wave-metal interactions was encoded to binary 0 and 1 for information encoding purposes. As a result, the reconfigurable micro-unit cell metamaterial tunneled structure was able to effectively control the electric field and allow electron packets to be digitally encoded for the information processing system.
Highlights
Materials with special characteristics like negative permittivity together with negative permeability cannot be found in nature
This study introduces a new reconfigurable metamaterial microstructure that works as a digital filter and is capable of performing bit sequencing conversion in the THz frequency spectrum
The electric field was primarily determined by the configuration of the tunneled micro-structure, whereby the modulated wave signal was encoded to binary output using the proposed meta-device
Summary
Materials with special characteristics like negative permittivity together with negative permeability cannot be found in nature. A coding metamaterial was developed by Cui et al [8] for the manipulation of the reflection, scattering, and diffusion of waves in the microwave spectrum They presented two types of unit cells with 0 and π phases which they named as 0 and 1. Shen et al [17] developed a coding metasurface for beamforming applications based on transmission whereby the transmitted field patterns depended upon the metamaterial bits of the particular meta-atom structure. Arbabi et al [21] in 2018, developed a FIGURE 1 | Proposed metamaterial (A) C-V unit cell, (B) V one arm bend, and (C) V two-arm bend structures. The stacked tunnel metamaterial device has six metamaterial array plates, whereby the distance between each plate was 10 μm
